Help me, please, to fix the work of biber. When I put in biblatex options backend=biber then during the compilation I get:

This is BibTeX, Version 0.99d (TeX Live 2010)
The top-level auxiliary file: test.aux
I found no \citation commands---while reading file test.aux
I found no \bibdata command---while reading file test.aux
I found no \bibstyle command---while reading file test.aux
(There were 3 error messages)

I just updated my TexLive 2010 at 23.05.2011 by the command tlmgr update --all
Maybe I do something wrong? Please, help.

Update (after PLK's comment)

This is usually due to the way Biber is 'packed' for portability. On first run, it has to extract various bits of code, and if this goes wrong or gets interrupted then you get errors like the one seen.

Well if you tell biblatex that you intend to use the backend biber (backend=biber) then you should do it and not call bibtex. With backend=biber biblatex puts the informations in a bcf file and not in the aux so it is not a surprise that bibtex can't find them.
